| Description: |
Professional 500W FM transmitter All-in-one 19inch 4U cabin Software
radio product DSP+DDS CD audio quality Big LCD displays all
the parameter Analog and digital (AES/EBU) audio signal input
Easy to use.

The
transmitter implements a digital FM modulator
module as its core, combining a RF power amplifier. DSP
& DDS are used to
execute all-digital processing, such as digital
filtering, pre-emphasis, pilot generation, stereo coding and FM
modulation. AGC circuitry is used to keep the set power stable.
High performance and very good
reliability has been proved by the large usage of ZHC-500W-TX
transmitters. These transmitters are very low cost and small
size.
